I use vinegar diluted with water. This seems to work best for my kitties. I remember one time when I had used Lysol with water to wash my kitchen floor and my RB Mittens had a bad reaction to it. It had irritated his pads. We had to bring him to the vets and that was the first thing the vet asked, "Did I use a new cleaner on the floor?" BINGO.
Had to put a special cream on his pads, twice a day, for a week. He was fine after that.
Needless to say, I don't use Lysol anymore and I close the kitchen door until the floor is completely dry, before I allow my kitties in there.

Interesting thread Bryan.
